Focused Ultrasound-Mediated Targeted Drug Delivery Combined with Neoadjuvant Therapy
What this trial is about
This study aimed to evaluate the feasibility and safety, and to observe early efficacy signals of the focused ultrasound mediated drug delivery system combined with SonoVue® in patients with HER2-positive breast cancer receiving neoadjuvant therapy by comparing its pathological complete response (pCR) rate with a matched historical cohort of HER2-positive breast cancer patients treated at our center.
